Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Armed with a computer model in 1935, one could probably have written the exact same story on California drought as appears today in the Washington Post some 80 years ago, prompted by the very similar outlier temperatures of 1934 and 2014.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

The Tea Party Comes Home

Listening to Scott Brown’s long, barely scripted acceptance speech last night, you had the refreshing sense that you were listening to an ordinary American, not to some political cut-out. Here’s a guy who campaigned in a pick-up truck with over 200,000 miles on the odometer, who listened to the voters and understood that they wanted not simply to block tax hikes but to lower taxes (and the last thing they wanted was for their taxes to pay terrorists’ lawyers bills!), who understood that even worse than the health care bill now before Congress were the back-room deals that brought it about, who’s served proudly for 30 years in the National Guard – in short, here’s guy you’d be comfortable having a beer with because, as he said, “I know who I am and I know who I serve.”

Which brings to mind the famous Rose Garden beer the president and vice president shared with Prof. Gates and Sgt. Crowley – speaking of (dis)comfort. And that brings to mind Cambridge, which stayed true blue, 84-15, Walter Russell Mead informs us this morning in his delightfully tongue-in-cheek Arena post. (“First, some good news for Democrats: the base is secure.”) As goes Harvard, so goes Berkeley.

But to today’s Arena question. The Democratic left is predictably outraged that “the people” they so love in the abstract have so disappointed them in the concrete. Exhibit A is last night’s Arena post by The Nation’s Katrina vanden Heuvel. Railing against “the Tea Party’s inchoate right-wing populism” (if it’s infested Massachusetts, shudder to think of it in Idaho!), Katrina tells Obama to “get tough, get bold, kiss ‘post-partisanship’ goodbye,” and “put yourself squarely back on the side of working people” by “passing the strongest possible healthcare bill as quickly as is feasible.” And there’s the cliff, Katrina.

Lanny Davis has more sober advice for Obama in this morning’s Wall Street Journal. To those who are pointing fingers at Martha Coakley, Lanny says, “This was a defeat not of the messenger but of the message” – the unrelenting leftism that has come from this White House and this Congress. And he points, by way of instruction, to Bill Clinton’s response to the disastrous elections of 1994, though he doesn’t mention Clinton’s ringing, albeit inaccurate, description of his course-change – “The era of big government is over.” Is it in Obama’s DNA to make such a course correction? Does he have a reset button?

On health care, Obama and his party are in an almost impossible situation. If they press ahead, as Nancy Pelosi and others are urging, the cliff awaits them in November. But if they abandon their project, what will they run on in November? It’s a mess of their own making, of course, so completely did they misread the election of 2008. What better evidence of the endurance of principles of sound, limited government that some two centuries later, The Tea Party has come home to Boston.
